Description

Description

The use of standard solutions can provide control of the laboratory process, increase confidence, and help provide a clear demonstration of performance to various inspectors, regulatory agencies and clients. One-parameter analysis can be performed on different analyzed samples and concentrations to confirm accuracy.

Nitrate Standard Solution (237842) from Hach. Concentration 100 mg/L as Zn (NIST).

Platform: Solution.

Summary of method: Zinc and other metals in the sample are complexed with cyanide. The addition of cyclohexanone causes a selective release of zinc. The zinc reacts with 2-carboxy-2'- hydroxy-5'-sulfoformazyl benzene (zincon) indicator to form a blue-colored species. The blue color is masked by the brown color from the excess indicator. The intensity of the blue color is proportional to the amount of zinc present.
